Well, the next two feature in ES6 are very interesting. Return this.name + " uses " + arrayToString(this.technology) You will feel familiar to this way if you come from a Java background or other OO language.
Instead, Javascript can simulate classes using functions and prototype.īelow is the new syntax to create classes. Look below the sugar syntax in action to create a class in Javascript.Īlways remember: Javascript does not support classes like other Object-Oriented languages. So instead of writing the your code using the old tricky way, you’ll be able to code in a the simpler way, with sugar syntax.
It also means that some “new” features of ES6 are not really new because ES6 is trying to simplify the syntax to make things easier for us. But instead of you spend too much time learning and researching all of the features I separated a few that I felt are the ones you’ll be probably using in your daily basis.ĭon’t worry if you are new to javascript or you’re coming from a server-side language, I believe this is the best time to learn it as ES6 has a much cleaner and friendlier syntax, known as sugar syntax.įirst of all, Syntactic Sugar is a syntax that make a language easier to understand and more readable, it makes the language “sweeter” for us.
The resulting color is now yellow.The next-generation of javascript also known as ECMAScript 6 (also called ES6 or Harmony), is bringing us lots of amazing features that you probably will need to know. Notice the properties that did not match were combined, but the property that did match, color, was overwritten by the last object that was passed, updateMyVehicle. React uses ES6 in some of the new features like:Ī class is a type of function, but instead of using the keyword function to initiate it, we use the keyword class, and the properties are assigned inside a constructor() method. It was created to standardize Javascript, and ES6 is the 6th version of ECMAScript, it was published in 2015 and is also known as ECMAScript 2015.
